This invention relates to improvements in winding machines and particularly to machines for winding so-called bottle bobbins used as supplies for knitting machines or for other purposes.

A principal object of the invention is to provide a winding machine of the type specitied which is capable of high speed operation and automatic in its control.

Another object of the invention is to provide a winding machine which, is adjustable for winding bobbins of difi' rent sizes and having automatically operate means for arresting the winding at the completion of the bobbin.

Another object of the invention is to provide a machine of the type specified which is simple in' construction, eflicient in operation and durable in use.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention as illustrated in the accompanying drawings. In the drawings:

Fig. 5 is a detailed view of a portion of the stopping-mechanism of the machine; and

Fig. 6 is a part sectionalplan view of the same.

Referring to Figs. 1 and 2 of the drawings, the machine in general comprises certain essential elements which are well known in the art. The operating parts of the machine are mounted on a box-like frame 2 carrying bearings for a horizontal winding-spindle 3 and a parallel cam-shaft 4 arranged therebelow. The winding-spindle 3 is driven from suitable power-operated means such as a beltpulley 6 connected by a clutch 7 The camshaft 4 is driven from a train of gearing, not herein shown, which is enclosed in a case or thread-guide which lays the yarn, thread or other strand material on the bobbin.

The traverse-mechanism is mounted on a traverse-frame 18 constituted by a horizontal bar or member 19 supported by opposite arms 20 and 21 which are pivoted to rock on the bearings 22 and 23 for the cam-shaft 4. The

forward arm 20 of the frame 18 is located outside of the end of the frame 2 while the opposite arm 21 is enclosed therein, the left hand side of the frame 2 being cut away with an opening 24 to adapt the traverse-frame to swing on the axis of the cam-shaft 4. The

traverse-frame 18 is also provided with an overhanging portion 25 project-ing outwardly beyond the arms 20 and forming an extension of its main horizontal member 19. The two horizontal parts 19 and 25 of the frame 18 are provided with a semi-circular groove 26, see Figs. 2 and 3, adapted to serve as a track or guideway for the sliding traverse-rod 27. The inner end of the traverse-rod 27 is connected to a slide 28 which carries a roller or bowl 330 engaged with thehelical groove 16 in the cam 15. I The outer end of the traverserod 27 carries an arm 31 connected to reciprocate the traverse-guide 35 in the manneras later described. 1

Attached to the outer overhanging extension 25 of the traverse-frame 18 is a supplemental framework 32 which is fastened in place by screws 33. The frame 32 has a bearing portion 34 abutting the side of the extension 25 on the frame 18 and formed on its lower edge with an arcuate groove 36, see Fig. 3, which serves to retain the traverse-rod 27 in the groove or guideway 26. Reaching upwardly from the frame 32 are opposite arms 37 and 38 forming bearings for a slidable rod -cation of the latter.

40, the arm 38 being extended in a quill-like bearing 39 through which the rod 40 slides.

The arm 31 on the traverse rod 27 is bent around at the top in a 'loop 41 enclosing'the rod 40 and clamped fixedly thereto by means of a screw 42. a

The reciprocable rod 40 is formed with partial screw-threads 44 adapted to be en-. gaged by an interiorly-threaded sleeve-like nut 45 formed with a flange 46, see Fig. 4. Secured fast to the flange 46 is a disk or progression-wheel 48 which is adapted to make contact with the bobbin being wound to feed the nut 45 along the rod 40 in the manner as well known in the art. Straddling the ends of the nut 45 is a yoke-shaped arm 50 carrying the thread guide35, previously referred to. The arm 50 'is formed at its upper end with a circular openin for receiv; ing the guide 35 which is of the utton type having a groove 51 for the thread, yarn or other strand to draw through. The upper end of the arm 50 is formed substantially as a fork having curved prongs 52 providing a reentrant-guideway for directing the strand into the groove 51 in the guide 35. Secured to a leg of the arm' 50 is a coiled spring 54 having its end extendin into position to press against the rim of t 1e flange 46 on the nut 45 to displace the latter eccentrically of the rod 40, whereby its interior threads are normally maintained in engagement with the threads 44 on the rod. Through this arrangement the turning of the contact-disk or progression-wheel 48 causes the arm 50 and its thread-guide 35 to be fed progressively outward along the rod 40- during the recipro- It is tobe understood that the bore of the nut 45 is larger than the diameter of the rod 40 so that by pressing the nut against the force of the spring 54 its threads may be released from those on the rod to permit the thread-guide to be pushed back along the rod to adjust it to proper position at the start of the winding. This construction and arrangement of the propelling means for the thread-guide are well known in the art and therefore needno further explanation.

As shown in Figs. 2 and 3, the thread-guide arm 50 reaches out toward the windingspindle 3 to adapt the button guide 35 to bear against the bobbin being wound; the arm being swiveled on the rod 40 to allow the guide to swing toward and away from the axis of the bobbin as it rides on the conical surface of the winding. The present machine, as before explained, is adapted particularly for winding bottle bobbins which are built up on a core or holder B of the form illustrated in Fig. 1. The holder B is usually constructed of wood with a frusto-conical base I) at the end of a substantially cylindrical barrel 7).. The holder B is bored axially to adapt it to be placed on the overhanging portion 55 of thewinding-spindle, this part being preferably made as an extension screwed into a bore at the end of the main spindle 3. This arrangement provides for detaching the spindle-extension 55 and substituting other extensions of different diameter and length in accordance with the dimensions of the bobbin to be wound. A sleeve 56 is secured to the end. of the main spindle 3 by means of a set-screw 57 to serve as a driver for the bobbin holder B, a key 58 in the end of the sleeve being engagable With a slot in the base of the holder as shown in Fig. 1. The outer end of the spindle-extension 55 is split and bored axially to receive an expanding-screw 60 having a taper-ended head which operates in the usual manner to expand the spindle to bind it in the bore of the holder B to secure the latter thereon.

The present machine is adapted to wind thread, yarn or other strand material delivering from a supply such as a skein arranged above the machine,'but not herein illustrated. In order to clean and clear the yarn or thread from lint, specks, motes and slubs before it is wound into the bobbin a slub-catcher and yarn-cleaner is applied to the thread-guide arm 50 to act on the strand as it leads through the guide 35. The yarn-cleaner or slubcatcher as herein shown comprises an angularly bent plate riveted or otherwise fastened to the back of the thread-guide arm 50 and projecting upwardly therefrom with a blade portion 66 reaching across the path of the yarn as it leads to the guide 35. A c0- operatlng blade 67 is pivotally mounted on the plate 65 at 68 and is adapted to be adjusted by means of a screw 69, see Fig. l, passing through a .slot, not shown, in the blade to set it with its edge in parallel spaced relation with the edge of the blade 66. In this way a slit is provided through which the yarn draws in leading to the thread-guide, the width of the slit being adjustable in accordance with the size or thickness of the yarn. A wire arm 70 is attached to the plate 65 by means of a screw 71 and reaches upwardly to support a porcelain guide-eye 72 at its end. The guide-eye 72 serves as a means for retainin the strand in position to draw between the lades of the slub-catcher as it feeds to the thread-guide 35.

It has been explained that the traverseframe 18 is mounted to swing on the axis of the cam-shaft 4, this arrangement being for the purpose of adjusting the position of the contact-disk or progression-wheel 48 with respect to the'axis of the windin spindle. Normally, during the operation 0 the machine, the traverse-frame 18 is locked in fixed position to maintain the contact-wheel 48 in such relation'to the axis of the windingspindle as to cause its periphery to bear on the winding at the point of greatest diameter of the bobbin. As the traverse-guide 35 is reciprocated with the rod 40 through the action of the cam 15 on the traverse-bar 27' B. The strand 3 of yarn or thread will thusbe traversed on the inclined surface of the base 6 of the bobbin B and each time the guide moves to its rearward extent of travel the'wheel 48 will contact with the yarn laid at the extreme base end of the bobbin, whereby the wheel is rotated to a slight extent to advance the guide to a new position on the bar 40. It will be obvious, therefore, that to provide for winding bobbins of different diameter the contact-wheel must be adjusted at varying distances from the axis of the winding spindle. The means for accomplishing this adjustment and for normally maintaining the contact-wheel in fixed relation with respect to the axis of the winding spindle during the winding are shown 'most clearly in Figs. 3, 5. and 6.

Attached to the side of the main frame '2 of the machine is a locking-member formed with an arcuate slot 76. The looking member 75 is fastened to the frame by means of a bolt 77 extending through its slot 76 whereby to provide for its adjustment to alter the position of the traverse-frame 18 in the manner as later explained. The member 75 is provided with an abutment 78 on its upper rim spaced at a distance from a detentshoulder 79 cut into the top of the member.

The detent-shoulder 79 is engaged by a square-edged stud or detent-block 80 which projects from a boss 81 on the side of a weighted arm 82, see Figs. 5 and 6. The. weighted arm 82 is fast on a rockable rod 83 extending longitudinally of the auxiliary frame 32 attached to the traverse-frame 18. As shown in Fig. 1, the rod 83 is held at its outer end in an arm 84 on the supplemental frame 32 and reaches through a bearing lug 85 depending from the over-hanging portion 25 of the main frame 18. At its rearward end the rod 83 projects through a. bearing in the leg 20 of the traverse-frame 18, see Fig. 6,

its terminal portion being engaged with a groove 86 cut into the forward face of the locking-member 75.

The weighted arm 82 is secured faston the rod 83 by means of a set-screw 87, and a boss 89 on the side of the arm abuts the side of the traverse-frame arm 20. A collar 90 is fastened to the rod 83 in position to abut the side of the lug 85 on the frame 18 and through this arrangement the rod 83 is held from longitudinal displacement in its bearings on the traverse-frame. While the machine is operating the detent-block 80 is engaged with the shoulder 79 on the locking-member 75 to hold the traverse-frame 18 in position with the contact-wheel 48 spaced at the proper distance from the axis of the winding-spindle, the contact-wheel being set in predetermined position by loosening the bolt 77 and adjusting the locking-member 75 as before explained. The above-described detent or lock for the traverse-frame 18 is adapted to be released to allow the contact-wheel 48 to move away from the bobbin at the completion of the winding through instrumentalities as next described. This release is effected by the action of the thread-guide 35 when the bobbin reaches its predetermined length, and thereupon the operation of the machine is arrested by the movement of the traverse: frame under the action of gravity.

Referring to Figs. 1 and 2 of the drawings, a stopping-lever 92 projects upwardly from the rockable rod 83 on the traverse-frame 18 and is formed'at the top with an angular head 93 adapted to be engaged by the beveled end 94 of the leg of the thread-guide arm 50. The stopping-lever 92 is formed with a hub 95 secured fast on the rod 83 by means of a set-screw 96. Through this arrangement the stopping-lever may be adjusted longitudinally of the rod 83 to set it in position to be engaged by the traverse-guide arm '50 to arrest the winding operation when the guide has progressed along the rod 40 to the extent required for winding the bobbin to its predetermined length. For bobbins of greater or less length the lever 92 is adjusted to dilferent positions along the rod 83.

The'stoppin g-mechanism for arresting the operation of the machine when the traverseframe is released to swing back from the winding-spindle is organized and arranged as next explained: It has been stated. that the belt-pulley 6 is connected to rotate the winding-spindle 3 through the medium of a clutch 7, and to arrest the rotation of the spindle the clutch is released from the pul-- ley by any suitable means such as that shown in Fig. 1 of'the drawings. As here illustrated the hub of the clutch 7 is provided with a groove 97 which is engaged by the end of a rockable lever 98. The lever 98 is pivoted at 99 to an arm 100 which is attached to the top of the frame 2. A rockable rod 101 is mounted in bearings 102 at the top of the frame 2 and at its forward end is a starting-handle 103 adapted for use in manually rocking the rod to shift the clutch into engagement with the driving-pulley 6. The

clutch-lever 98 is formed with a cam-slot 104 which is engaged by a stud or pin 105 projecting from a collar 106 secured to the end of the rod 101. Referring to Figs. 1 and 2, when the starting-handle 103 is rocked in the direction indicated'by the arrow in Fig. 2 the collar 106 will be rocked to cause the stud 105 to act in the cam slot 104 to rock the lever 98 to throw the clutch 7 into engagement with the driving-pulley 6. On the other hand, when the handle 103 is rocked in the'opposite direction the" clutchlever 98 will be actuated to withdraw the clutch from en agement with the drivingpulley. A suita 1e spring, not herein shown, acts to-rock the rod 101 to release the clutch.

The rockable rod 101 and the starting-handle 103 are'held in. the position shown in Fig. 2 to maintain the machine operative by means of a well-known form of detent-mechanism shown in detail in Fig. 3 of the drawings. Pivoted to the side of the frame 2 of the machine bymeans of a screw 107 is an arcuate member or quadrant 108 disposed in concentric relation with respect to the axis of the traverse-frame 18. Projecting upwardly from the quadrant 108 is an arm 109 formed with a detent-shoulder 110 adapted to be engaged by a lug 111 which is carried by a. sickle-shaped arm 112 reaching down from the starting-handle 103. As shown more particularly in Fig. 1, the arm 112 has a hub 113 which is'secured fast to the rockable rod 101 abutting the front of the bearing 102. The hub 113 is provided with-lugs 114 between which the starting-handle 103 is secured by means of a cross-pinll5.

With the lug 111 engaged with the detentshoulder 110, asshown in Fig. 3, the starting-handle 103 is held in position to maintain the machine operative as-before explained and to arrest the winding operation the detents are disengaged by lifting the outer end ,of the uadrant 108. The release of the detents al owe the rod 101 to be rocked under the influence of a spring, not herein shown, thereby causing the operation of the clutchlever 98 in the manner as before explained. The lifting of the quadrant 108 is effected by the swinging action of the traverse-frame 18 when its lock is released, the instrumentalities for performing this operationbeing arranged as next vdescribed. Conveniently, a wedge-element116 is attached to the outer end of the quadrant 108 at 117 and arranged with its lower beveled edge 118 in position to' be engaged by the rounded edge 119 on the traverse-frame 18, see Fig. 3. The wedge 116, is adjustable on the quadrant 108 so that it may be set in accordance with the setting of the traverse-frame 18 whereby only a slight movement of the latter is required to effect the release of'the detents which control the stopping-mechanism of the machine.

Secured to the side of the main frame 2 is a stop-member 1 20 held in place by a bolt 121 extending through a slot 122- therein. The stop-member 120 has an abutment 123 adapted to be engaged by a depending portion 125 on the traverse-frame arm 20 to limit the outward throw of the upper part of the frame 18 when the latter is released from its lock. The stop-member 120 relieves the thrust of the frame on the wedge-member 116, being adjustable in position to engage the frame after it has acted to lift the quadrant 108.

The method of operation of the complete machine will now be explained in detail. A suitable holder B is placed on theiwindingspindle extension 55 and securedthereto by means of the expansion-screw 60. The traverse-frame 18 is then adjusted in position to bring the periphery of the contact-Wheel 48 in proper relation with respect to the base 0 of the bobbin-holder B to adapt it to contact with the first layer of yarn or thread wound thereon, the locking-member being adj usted in position in the manner as before explained for this purpose. With the traverseframe 18 looked through the engagement of its detent-block with the shoulder 79 on the member 75 the machine is ready for operation. The strand of yarn or thread 3 is led down through the uide 72 and thence drawnbetween the bla es 66 and 67 of the slub-catcher and through the guide 35, its end being suitablyattached to the holder B- It is to be umderstood, ofcourse, that at the start of the winding the thread-guide 35 is set back in position as shown in Fig. 1 so that it will traverse opposite the base 6 of the bobbin B. this adjustment being accomplished by disengaging the nut45 from the threads 44 on the rod 40 to allow the guide arm 50 to be slid on the rod in the manner ,as previously explained. V

The starting-handle 103 is now rocked in the direction indicated by the arrow in Fig. 2 whereby to cause the lug-111 on the arm 112 to. be locked with the detent-shoulder 110 on the quadrant 108. This operation of the starting-handle 103 causes the clutch 7 to be engaged with the driving-pulley 6 to connect the latterto rotate the winding-spindle 3 and, through the connections previously explained, to drive the cam-shaft 4. The spindle 3 rotates the bobbin-holder B to wind on the yarn feeding through the thread-guide 35 and the cam 15 is driven to cause the traverse-rod 27 to be reciprocated longitudinally in its guideway in the traverse-frame 18. The traverserod 27 reciprocates the threaded rod .40 through the medium of the connecting arm 31, and thereby the guide 35 is traversed longitudinally of the axis of the winding-spindle to an extent equal to the length of the base I) of the bobbin -holder B. The yarn or thread y is thus traversed first on the lnclined surface of the base I) of the holder B and as the progression-wheel contacts with the winding at I 40 and eventually reaches a position near the tip of the holder B the guide-arm 50 is caused to engage the inclined head 93 on the lever 92 during the forward stroke of the guide, whereby to rock the lever to the right as viewed in Fig. 2. The rocking of the lever 92 in this manner acts through the rod 83 to lift the weighted arm 82 whereby to release its detent-block 80 from the detent-shoulder 79 on the locking-member 75. Upon the release of the detents 79 and 80 in the manner as above explained the traverse-frame 18 will swing back under the action of gravity until its rounded portion 119 engages under the beveled edge 118 of the wedge-member 116, see Fig. 5. This engagement causes the outer end of the quadrant 108 to be pried upwardly to release the lug 111 from the detent-shoulder 110 whereby to free the arm 112. Upon the release of the arm 112 the starting-handle 103 will be caused to swing back in the direction opposite to that indicated by the arrow in Fig. 1 and this action will effect the withdrawal of the clutch 7 from the driving-pulley 6 to arrest the operation of the machine in the manner as before explained. lVhen it is required to start the machine again to wind a new bob-' bin the guide is once more adjusted back to first position on the rod the traverseframe 18 locked to the member 75; and the starting-handle 103 moved manually to again engage the lug 111 with the detent 110 to shift the clutch 7 into driving connection with'the Y pulley 6.

It will be observed from the above that my invention provides a particularly simple and eihcient machine for winding bottle bobbins of various sizes. The machine is automatic in its control and may be adjusted to wind bobbins of any desired diameter and length.

In a winding machine, the combination of means for rotating a cop or bobbin, means for traversin strand material thereon, contact-means a apted to be operated from the rotation of the cop or bobbin to eflect a relative displacement between the traversingmeans and the cop or bobbin to advance the layers of winding longitudinally thereof, automatically operated means for arresting the rotation of the cop or bobbin and the operation of the traversing-means, and means operated concurrently therewith to remove the contact-means from the bobbin.

In testimony whereof I hereunto afiix my signature.
